Mobile devices having fax capabilities

ABSTRACT

Devices, systems and methods are disclosed which relate to incorporating a fax machine function into a mobile device. A camera on the mobile device is used to scan or capture an image of an existing document. Logic on the mobile device converts the image into a fax transmittal that can be transmitted to a fax machine. Once the fax transmittal is ready, a connection is initiated with a traditional fax machine across one or more networks, and the fax transmittal is sent to the fax machine at a speed determined by the slower device. Upon a successful transmission, the connection is terminated, and a report is generated.

CROSS-REFERENCE TO RELATED CASES

This application is a continuation of and claims priority to U.S. patentapplication Ser. No. 12/820,994 entitled “Mobile Devices Having FaxCapabilities,” filed on Jun. 22, 2010, now U.S. Pat. No. 8,433,365,which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to mobile devices. In particular, thepresent invention relates to sending and receiving fax transmittalsusing mobile devices.

2. Background of the Invention

The old faithful standby for transferring copies of existing paperdocuments across networks is the facsimile (or fax) machine. Faxmachines have existed since the 1970s, and are still in use today.Generally, a fax machine has an image sensor that uses light to scan amaterial to be faxed, a fax modem that converts the scanned data intodigital format or vice versa, a phone line for the transmission of thefax transmittal, and a printer that produces printouts of receivedfaxes. Various compression techniques can be used to transmit the faxtransmittal across a telephone line. The data is transmitted usingelectrical pulses that represent black and white dots on the scannedimage, wherein the fax transmittal is reproduced at the destination byprinting dots corresponding to the received pulses. Fax machines set upconnections with each other across telephone lines by using a“handshake” where the machines agree on a speed and a type oftransmission.

Fax technology has faced increasing competition from internet basedalternatives. Specifically, mobile devices, e-readers, and broadbandnetworks enable exchange of information in all forms. The speed oftransmission over modern network, such as an Internet Protocol (IP)network, is several magnitudes faster than the speed at which faxmachines communicate. However, fax machines still retain someadvantages. Sensitive material transmitted over the internet couldpotentially be intercepted. Further, the laws of some countries do notrecognize electronic signatures, while faxed contracts with copies ofsignatures are valid. Moreover, a general mistrust of electronic devicesexists and stems from hard drive failures, network failures, datacorruption, etc., resulting in additional comfort and safety by relyingon paper copies. Therefore, fax machines enjoy continued support inbusinesses.

However, fax technology has not evolved much relative to the evolutionof mobile technology. Fax machines are bulky, tied to land lines, andtherefore immobile. Further, they are not ubiquitously available. Forinstance, a corporate user cannot easily access fax machines whiletraveling. Several other drawbacks inherent to faxes will be recognizedby one of ordinary skill in the art.

Existing methods to mitigate these drawbacks include sending faxes overthe internet, using mobile devices as fax modems, Fax over IP (FoIP),etc. For instance, a user can scan and upload a document to a fax serveracross a network. The fax server transmits the fax to a traditional faxmachine using known techniques. Alternatively, a mobile device can becoupled to a computer to be used as a fax modem. The computer uses themobile device as a network interface to dial out to the fax machine andtransmit the scanned image to the destination fax machine. Fax over IPinvolves sending packets of data across an IP network to anotherIP-enabled destination, wherein the received packets are used toreconstruct the image and print the transmittal.

However, these known techniques have their own issues. For instance,faxing over the internet requires, first, an internet connection.Second, it requires a user to upload the fax transmittal to a secondaryserver on the internet. Besides the obvious security issues involved,this still requires the use of an intermediary between the source anddestination, and is therefore not as faithful or ideal to the originalfax method that uses a direct connection between the two devices. Inaddition, using the phone as a modem has its own issue, namely, that twodevices are used to send the fax: a computer, and a mobile device.Further the computer needs to be coupled to a scanner in order toconvert an existing paper document into a fax transmittal. Finally, Faxover IP requires that both source and destination devices be IP-enabled.This renders FoIP incompatible with existing fax machines in use today.

What is needed, therefore, is the ability to create and transmit faxtransmittals from a mobile device to another device across a network,including fax machines.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a novel technique for creating a faxtransmittal from a document and sending the fax transmittal to adestination device across a network, using a mobile device. The mobiledevice includes a camera to capture an image of the document to betransmitted. An application or user interface on the mobile deviceenables a user to adjust the scanned image in several ways, includingselecting a page size of the fax transmittal. Annotations, signatures,and cover sheets can be added to the fax transmittal. A fax logic on themobile device initiates a connection with the destination device acrossthe network, for instance, by dialing out to a fax machine. Uponanswering, a handshake operation between the two devices is performed toset up a connection. When connected, the fax logic transmits the faxtransmittal to the fax machine at a speed determined by the handshakeoperation. Upon completion, a report can be generated.

The user is additionally provided with an option to transmit the faxtransmittal to a plurality of addresses on different networks. Forinstance, the user can send a copy of the fax to an e-mail address, orto another fax machine. The user can queue the fax transmittals,schedule the sending for a later time, etc. The invention furtherfeatures a fax receiving mechanism whereby an incoming connection isdetermined to be from a fax machine. The incoming fax transmittal fromthe fax machine is decoded at the mobile device, and can be displayed ona display of the mobile device, stored to e-mail, and/or printed on aprinter.

As used herein and throughout this disclosure, the term “mobile device”refers to any electronic device capable of wirelessly sending andreceiving data across a network. A mobile device may have a processor, amemory, a transceiver, an input, and an output. The memory storesapplications, software, or logic. Examples of processors are computerprocessors (processing units), microprocessors, digital signalprocessors, controllers and microcontrollers, etc. Examples of devicememories that may comprise logic include RAM (random access memory),flash memories, ROMS (read-only memories), EPROMS (erasable programmableread-only memories), and EEPROMS (electrically erasable programmableread-only memories).

“Logic” as used herein and throughout this disclosure, refers to anyinformation having the form of instruction signals and/or data that maybe applied to direct the operation of a processor. Logic may be formedfrom signals stored in a device memory. Software is one example of suchlogic. Logic may also be comprised by digital and/or analog hardwarecircuits, for example, hardware circuits comprising logical AND, OR,XOR, NAND, NOR, and other logical operations. Logic may be formed fromcombinations of software and hardware. On a network, logic may beprogrammed on a server, or a complex of servers. A particular logic unitis not limited to a single logical location on the network.

A mobile device also includes a transceiver to connect to a network. A“network” can include broadband wide-area networks, local-area networks,and personal area networks. Communication across a network is preferablypacket-based; however, radio and frequency/amplitude modulationsnetworks can enable communication between communication devices usingappropriate analog-digital-analog converters and other elements.Examples of networks include cellular, General Packet Radio Service(GPRS), Wi-Fi, and Bluetooth® networks. Networks also include plain oldtelephone service (POTS), public switched telephone networks (PSTN),etc. Networks can include a plurality of elements that host logic forperforming tasks on the network such as setting up connections betweendevices. Networks can further include servers or elements such asgateways that enable communication between two different types ofnetworks. An example of a gateway is a GPRS support node (GSN). Mobiledevices may have more than one transceiver, capable of communicatingover different networks, for instance, a GPRS transceiver forcommunicating with a cellular base station, a Wi-Fi transceiver forcommunicating with a Wi-Fi network, and a Bluetooth® transceiver forcommunicating with a Bluetooth® device. Further, mobile devices may makeuse of network interfaces to enable a particular transceiver tocommunicate with the particular network. An example of a networkinterface is a Subscriber Identity Module (SIM) card for cellularnetworks.

A “fax machine” is any hardware or software that is capable ofcommunicating across a network using International TelecommunicationUnion (ITU-T) standards. This includes, but is not limited to, group 1and 2 analog transmission, group 3 and 4 digital transmission andcompression, and so on. Further, a “fax machine” can be incorporated inany existing device, as will be evident in light of this disclosure.Conversely, a “traditional fax machine” is one that exists in theconventional art, described in the background section above, and will beidentified as such throughout this disclosure. A fax machine is used totransmit documents across a network. A “document” includes anycombination of text and images that can be photographed by a digitalcamera and transmitted as a fax transmittal.

For the following description, it can be assumed that mostcorrespondingly labeled structures across the figures (e.g., 132, 232and 332, etc.) possess the same characteristics and are subject to thesame structure and function. If there is a difference betweencorrespondingly labeled elements that is not pointed out, and thisdifference results in a non-corresponding structure or function of anelement for a particular embodiment, then that conflicting descriptiongiven for that particular embodiment shall govern.

FIGS. 1A-1C show the components of a mobile device 100 having faxcapabilities, according to an exemplary embodiment of the presentinvention. With respect to FIG. 1A, mobile device 100 includes a display102 and antenna 104. Display 102 is a touchscreen, and therefore can beused as both an input and an output device. Antenna 104 converts radiowaves into electrical signals to be received by a transceiver 108.Antenna 104 is shown to be external but can also be encased within ahousing of mobile device 100. FIG. 1B shows the back side of mobiledevice 100. A camera 106 is included, and is used as an optical scannerto capture images of documents to be faxed. Camera 106 can include anystandard digital camera lens and charge-coupled device (CCD), or anyother camera known in the art. Camera 106 can include an LED or similarflash (not shown). FIG. 1C shows the inner components of mobile device100. These include but are not limited to: CCD (which may be coupled toand/or be a part of the camera 106), transceiver 108, processor 112,memory 114, imaging logic 115 and fax logic 116. The camera 106, thetransceiver 108, the processor 112, and the memory 114 are known in theart and need not be described in great detail. Suffice to say,transceiver 108 enables communication with external networks via antenna104. Memory 114 stores logic that instructs processor 112 to operate thevarious components of mobile device 100, and to present a user interfaceon display 102. Besides imaging logic 115 and fax logic 116, other logicsuch as operating systems, applications, telephone software, etc. can bepresent, is well known, and need not be described. Further, otherfeatures can also be included and are not shown, such as slide-outkeyboards, projectors to project an image, camera flashes, GlobalPositioning System (GPS) units, accelerometers, and so on.

Imaging logic 115 comprises applications that enable a user to operatecamera 106, and to make any adjustment to the captured image. This isaccomplished by a user interface further described below. Briefly, auser is presented with alignment tabs, such as alignment lines or analignment grid, which can be used to line up a document in view ofcamera 106, and capture the aligned document image. Once captured, thedocument image can be adjusted with respect to cropping edges, andscaling the image to a pre-defined page size. This is useful so as toconform to requirements of the user or of the receiving entity.Brightness and contrast adjustments are also possible. Imaging logic 115can also include Optical Character Recognition (OCR) software to detectalphanumeric characters in the scanned document. Imaging logic 115 canalso include notation abilities. These enable a user to add annotationsto the scanned image, such as notes, highlighting, underlining, etc. Auser is also provided with an ability to add his or her signature to theimage, for instance, using a finger or a stylus on display 102. Otheroptions are possible, such as the addition of a cover page to the image.An adjusted image, along with any annotations, signatures, and coversheets, becomes a fax transmittal.

Once ready, the fax transmittal is passed on to fax logic 116. This canbe performed by deciding to “send” the transmittal. The user is promptedto dial a number or select a number from an address book. Fax logic 116uses transceiver 108 to initiate a connection with the selected numberor address over a network. For instance, fax logic 116 dials a phonenumber of a fax machine on a PSTN network. One or more network elementsmay be traversed in order to initialize/set up the connection. Thisincludes signaling between elements, wherein the signals includedialing, receiving a ringtone, answering, acknowledgements, etc. Oneexample of such signaling across a PSTN network is SS7 signaling. Upondetecting that the destination device has answered, a handshakeoperation is initiated between mobile device 100 and the destination faxmachine. The handshake operation consists of a series of signalstransmitted back and forth, negotiating a type, a speed, compression,and other attributes of the connection. Upon completion of thehandshake, fax logic 116 begins transmitting the fax transmittal to thedestination fax machine. This transmittal can emulate a standard faxtransmittal known in the art. One or several pages of the faxtransmittal are transmitted using these methods. Upon completion, afinal acknowledgement signal is transmitted, and the connection is torndown.

In further embodiments of the present invention, the mobile deviceincludes a fingerprint scanner. A user may scan his or her fingerprintto provide further authentication of the user. The fingerprint of theuser may be used in lieu of or in addition to the signature capturecapability of the mobile device. Alternatively, the fingerprint scannermay provide access to the faxing application. Such a feature may preventunauthorized users from sending a fax from the mobile device.

FIG. 2 shows a system for sending and receiving faxes using a mobiledevice 200, according to an exemplary embodiment of the presentinvention. Mobile device 200 communicates with fax machine 240 acrossnetwork 230. Initiation of a connection 234 between the two devices isfirst accomplished by signaling 232, which could be SIP signaling, SS7signaling, or any other protocol for setting up a connection based onthe type of network being traversed. For instance, network 230 is a PSTNnetwork, in which case SS7 signaling is used. When network 230 is an IPMultimedia System (IMS) network, SIP signaling may be used. Otherexamples are possible. In either instance, connection 234 is a directconnection between the two devices, and allows mobile device to send faxtransmittals bit by bit or line by line to fax machine 240. Conversely,fax machine 240 can initiate a connection with mobile device 200 usingsignals 232, and initiate connection 234 across network 230. Fax machine240 would transmit a scanned image of a document across connection 234to mobile device 200, using the ITU-T protocols described above andknown in the art. Mobile device 200 would then decode the received data,and reconstruct an image on its display. Optionally, the received imagecould be sent to a printer, to an email address, or stored locally onmobile device 200, including any external memory or storage currently inuse by mobile device 200.

FIG. 3 shows a system for transmitting faxes across a variety ofdevices, according to an exemplary embodiment of the present invention.The system includes a mobile device 300 for sending and receiving faxes.Mobile device 300 is in communication with radio 320, enablingcommunication with a service provider's network 336. Further, mobiledevice 301 is also in communication with service provider's network 336via radio 321. Another mobile device in this system is satellite phone303, in communication with the service provider's network 336 via ageosynchronous satellite 350. Finally, a traditional fax machine 340 isin communication with the service provider's network via a PSTN network338. It will be understood that several additional elements are includedfor this system to function, but are not shown. For instance, radionetwork controllers mediate communications between radios 320-321 andservice provider's network 336. For instance, gateways such as GSNsmediate communications between the service provider's network 336 andPSTN network 338. Other servers such as proxy servers, media servers,etc. will be apparent to one skilled in the art when implementing thepresent invention in different network environments such as IMS,long-term evolution (LTE), etc.

The present invention is able to provide a fax sending and receivingmechanism in each one of devices 300, 301, 303, and 340. Mobile devices300, 301, and 303 include a camera or other image sensor for capturingan image of a document to be faxed. Further, each of mobile devices 300,301, and 303 include a user interface to adjust the captured image toconform to a page size for sending fax transmittals, as well as to addannotations, signatures, and cover pages. A fax logic on each of mobiledevices 300, 301, 303, initiates a connection with a destination devicevia the service provider's network 336 and other elements. A directconnection is set up between the source and destination. If thedestination is one of the mobile devices 300, 301, and 303, then thedirect connection could be an IP-based connection. In this case, faxmachines within each of the mobile devices 300, 301 and 303 negotiate aconnection speed and type with each other. Further, if the serviceprovider's network 336 is IP-enabled, the mobile devices 300, 301 and303 can use fax over IP. In case fax machine 340 is one of the partiesto the connection, a direct connection is set up between one of themobile devices 300, 301, and 303, and fax machine 340, and a handshakeoperation is used to determine the speed and connection type of faxmachine 340. Either source device will adjust a sending or receivingspeed to conform to the requirements of fax machine 340.

FIG. 4 shows a method for transmitting a fax from a mobile device,according to an exemplary embodiment of the present invention. Accordingto the method, an image is captured S451 using a camera incorporatedwithin the mobile device. The image is usually of a document; however,the image can be of any object that is capable of being reproduced in ablack and white printout at a destination device. Capturing the imageS451 can include lining the image up with alignment tabs displayed on auser interface on the mobile device, and then activating a shutter. Theimage is stored in any known format on the mobile device having thecamera, and then can be adjusted S453 using any number of adjustmenttools provided by the user interface. For instance, a user may elect tocrop or resize S455 the image to conform to a particular page size, suchas A4, or letter. If no adjustment is needed, or after adjustment iscomplete, the user is given an option to append annotations S457 to theimage. The user may choose to append annotations, a signature, or acover page S459 to the image. All, some, or none of these options can beexercised. After an image is adjusted and/or annotated, the resultingproduct becomes a fax transmittal S461. The fax transmittal can have aspecific number of pages. All the pages are elected to be transmitted toa recipient S463. If more recipients are selected S465, then therecipients are added to a recipient list. Recipients can include phonenumbers of fax machines over a PSTN network or combination of networks,as well as other addresses such as SIP addresses, e-mail addresses, etc.A connection is initiated S467 with each destination address. Fortraditional fax machines, this involves dialing a phone number of thefax machine, handshaking with the fax machine, and transmitting the faxtransmittal S469. Other types of fax machines involve their own settingup, handshaking, and transmission procedures.

FIG. 5 shows a method for receiving a fax at a mobile device, accordingto an exemplary embodiment of the present invention. An incomingconnection is received S571 at the mobile device. The incomingconnection S571 is received across a network, and can occur in manyforms. In this instance, a determination is made S573 as to whetherincoming connection is an Internet Protocol (IP) connection or anordinary phone call. If the incoming connection is an IP connection,then a packet header is parsed S575 to determine a source of theconnection. A source can identify itself as a fax machine on anotherentity or device, and if this determination is made S575, then the faxis received and displayed S583 on the mobile device. However, if theincoming connection is a regular call, then a user is provided with aprompt of whether to answer, ignore, or answer as fax S577. Answering asfax is useful when the user knows that the incoming call is a fax call.Alternatively, answering as fax can be an automatic feature if it isdetermined that the incoming call is from a fax number, thisdetermination being made by a fax receiving logic within fax logicreferring to a phone book on the user's mobile device.

When answered in fax mode, the handshake operation S581 begins, todetermine a connection type and speed for receiving the fax. On theother hand, when answered in a regular mode S579, the signals that arereceived upon answering are monitored. Fax logic on the mobile devicedetermines that the received incoming call is, in fact, from a faxmachine. This can be done by listening for a handshake signal from thecalling device. Once determined as a fax, the handshake operation S581begins. Handshake operation enables a connection of a certain type andspeed to be set up between the two devices, upon which the fax isreceived S583 on the mobile device and displayed on a display of themobile device. Other options may be offered, i.e. to print, email, orforward the fax. Once received, the connection is terminated S585.

FIG. 6 shows a user interface for scanning a document on a mobile device600, according to an exemplary embodiment of the present invention. Inthis embodiment, a user desires to send a fax using mobile device 600.The user aligns mobile device 600 such that a camera of mobile device600 is located above a document. The document, in this instance a faxcover sheet, is seen as a document image 688 on display 602 of mobiledevice 600 while mobile device 600 is running an image logic. Alignmenttabs 686 on display allow the user to align the document properly sothat the corners of document image 688 are placed just within alignmenttabs 686. Alignment tabs 686 ensure that an image is created of theentire document. The spacing of alignment tabs 686 may be set when theuser chooses a size of the paper of the document. Alignment tabs 686 mayalso provide a grid, alignment lines, etc. to assist the user inalignment of the document. With document image 688 properly aligned, theuser presses an image capture button 689 to take a picture of thedocument. This captures document image 688 and saves document image 688to a memory of mobile device 600. In embodiments of the presentinvention, when document image 688 is positioned properly, the imagelogic automatically captures document image 688.

Once the image of a document is captured, the image may require editing.For instance, the user may desire to crop a portion of the image, maydesire to write into a portion of the image (such as when the image is aform and/or a signature is desired to be added to a signature line onthe form), may wish to erase a portion of the image, etc.

FIG. 7 shows a user interface for annotating a scanned image on a mobiledevice 700, according to an exemplary embodiment of the presentinvention. In this embodiment, a document image 788 has already beencaptured from a document using an optical sensor of mobile device 700,or has otherwise been uploaded to mobile device 700. Document image 788is seen completely within alignment tabs 786 on display 702, as portionsof document image 788 within alignment tabs 786 are to be part of a faxtransmittal. Image logic on a memory of mobile device 700 allows theuser to edit document image 788. The image logic includes features toadd to or delete from document image 788. Erase button 790 allows theuser to erase portions of document image 788. The user may select erasebutton 790, and then, for instance, scroll a finger across portions ofdocument image 788 to erase the portions. Write button 791 allows theuser to make additions such as notations to document image 788. The usermay select write button 791, and then, for instance, sign on a signatureline of document image 788.

Embodiments of the faxing application allow the user to enlarge aportion of the document image before editing the document image. Forinstance, the faxing application may allow the user to zoom in on thesignature line of the document image. The user may then use a stylus, orhis or her finger, to sign on the signature line. The user may also zoomin on a portion of the document image in order to erase a portion moreprecisely. In embodiments of the present invention, the user may use akeyboard or keypad of the mobile device to enter text into the documentimage. This may be useful, for instance, to fill out a blank fax coversheet form that has been captured through the optical sensor.

FIG. 8 shows a user interface for transmitting a fax on a mobile device800, according to an exemplary embodiment of the present invention. Inthis embodiment, a user is prompted with faxing options on a display802. Faxing options include create coversheet 892, send copy to e-mail893, multiple addresses 894, and next 887. Create coversheet 892 allowsthe user to create a coversheet for a fax transmission from the choiceof one of a plurality of stored coversheets. Once the user has chosen acoversheet, the user may edit the coversheet using an application suchas an application within image logic shown in FIG. 7. Send copy toe-mail 893 provides a checkbox allowing the user select to send a copyof the outgoing fax to the user's e-mail account. The user's e-mailaddress may be already stored on mobile device 800, a fax applicationwithin fax logic may prompt the user for the e-mail address, etc.Multiple addresses 894 allows the user to send the outgoing fax tomultiple addresses. These multiple addresses may include fax numbers,phone numbers of devices with similar faxing applications, e-mailaddresses, etc. Multiple addresses 894 and send copy to e-mail 893 bothinclude checkboxes to select each option. However, any other means ofselecting such an option are also possible. Multiple addresses 894 alsoincludes an entry box 895 for entering the destination addresses. Whenan outgoing fax is sent to these addresses, the faxing applicationarranges the addresses into a queue and sends each address the outgoingfax. Entry box 895 may take any form of selecting or entering addresses.Entry box 895 may allow selections from an address book, such as in ascroll menu, a series of checkboxes for contacts, may open a new windowon mobile device 800, etc. Next 887 allows the user to accept changes tothe fax options and instructs the fax application to take the user tothe next page. Alternatively, next 887 accepts the changes to the faxoptions and sends the outgoing fax.

FIG. 9 shows a user interface for receiving a fax on a mobile device900, according to an exemplary embodiment of the present invention. Inthis embodiment, an incoming connection 996, such as a call or fax, isincoming to mobile device 900. Incoming connection 996 causes fax logicon mobile device 900 to prompt the user with options for receiving thecall. Options include answer 997, answer with fax 998, send fax toe-mail 999, and ignore call 984. If the user does not know the callingparty, or knows that the incoming connection is a phone call, the userpresses answer 997. Answer 997 creates a voice connection between mobiledevice 900 and the device requesting communication. If the user knowsthat the incoming connection is a fax, the user does not want to createa voice connection. The user presses answer with fax 998 to allow ahandshake between mobile device and the sending device followed by thefax transmittal. The fax may then be decoded and displayed on display902 of mobile device 900. If the user knows that the incoming connectionis a fax and wishes the fax to be sent to the user's e-mail, the userpresses send fax to e-mail 999. This similarly allows the handshakebetween mobile device 900 and the sending device, and allows the faxtransmittal, but the fax transmittal is delivered directly to the user'se-mail account. Further, the user may wish to not receive an incomingcall or fax. To ignore an incoming connection, the user may press ignorecall 984. Pressing ignore call 984 with an incoming fax refuses thehandshake and the fax transmittal. In embodiments of the presentinvention, ignore call 984 automatically sends a reply to the sendingdevice notifying the sending device to resend the fax at a later time.Pressing ignore call 984 with an incoming voice connection may, forinstance, turn off the ringer of mobile device 900 and connect thecaller to a voicemail box for mobile device 900.
